Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for mounting a control circuit board of a magnetic card reader device in a cashless public telephone using a magnetic card.

In recent years, telephones (commonly known as cashless public telephones) have been proposed in which calls can be made by inserting a magnetic card instead of inserting coins. This is done by installing a magnetic card reader device inside the phone case.
While transporting the magnetic card inserted through the slot, the magnetic information recorded on the magnetic film of the magnetic card is read out to confirm the remaining power of the magnetic card, allowing a call, and after the call is over, the remaining power is rewritten. The system is such that the magnetic card is returned to the user after this process has been completed.

Therefore, this magnetic card reader device includes a magnetic card reader mechanism section that mainly includes card running path constituent members that take in, read/write, return, store, remove, etc. the magnetic card inserted from the insertion slot; The magnetic card reader control circuit unit controls each of these operations, but each operation in the magnetic card reader device is controlled in an extremely complicated manner, and the mechanical unit and circuit unit have complex electrical Because they are connected, the two are almost incompatible, and in order to resolve a malfunction in a certain part of either, both must be replaced.

Therefore, when this kind of magnetic card reader device that has been proposed in the past is installed in the case of a cashless public telephone, it is very important to decide how to arrange the magnetic card reader mechanism section and the magnetic card reader control circuit section. This has become a difficult problem, and it is necessary to mount multiple magnetic card reader control circuit boards at multiple appropriate locations inside the casing, and mount the magnetic card reader mechanism separately inside the casing. Conventional methods have had various problems such as the maintenance, inspection, and repair work of the magnetic card reader device being extremely complicated, and the assembly work of the cashless public telephone being also complicated and occupying a large amount of mounting space.

The present invention was developed in view of the above circumstances, and attempts to solve the above-mentioned problems by connecting and fixing the magnetic card reader control circuit board to the magnetic card reader mechanism part as an integral structure. It is something.

An embodiment of the present invention will be described below with reference to the drawings.

Figures 1 and 2 show an embodiment of the present invention.

In the figure, 10 indicates a magnetic card reader mechanism section, and 20 indicates a magnetic card reader control circuit section.

The magnetic card reader mechanism section 10 has a card running path for taking in and transporting a magnetic card from a magnetic card insertion slot 11a at the top of the front to a magnetic card return slot 12a at the bottom of the front. The outer frame plates 13 and 14 facing each other in parallel are connected and fixed by horizontal shafts 16 and 17, and an insertion slot provided with the magnetic card insertion slot 11a is provided between the upper parts of the outer frame plates 13 and 14. A board 11 is fixed, and a return slot device 12 including the magnetic card return slot 12a is fixed between the lower portions of the outer frame boards 13 and 14.

The magnetic card reader control circuit section 20 consists of magnetic card reader control circuit boards 21, 22, and 23 in which electronic components (not shown) are mounted on a plurality of printed boards. Among these control circuit boards, one control circuit board 21 has almost the same shape as the outer frame 13,
They are erected in parallel on the outside of the outer frame body 13 at a predetermined interval and fixed via connecting rods 31, 31, . . . . The other two control circuit boards 22 and 23 have almost the same shape as the lower part of the outer frame board 14 so as not to contact the mounted components (indicated by dotted lines) 15 protruding from the upper part of the outer frame board 14. , are fixed to the outside of the outer frame plate 14 at predetermined intervals via connecting rods 32, 32, . In this way, the magnetic card reader mechanism section 10 and the magnetic card reader control circuit boards 21, 2
2 and 23 have substantially the same shape so as not to increase the overall size as much as possible, and are connected and fixed as an integral structure, and the mechanism section 10 and the circuit section 20 are electrically connected by wiring.

The magnetic card reader control circuit board 21 is also provided with a connector 24 for connection to an electric circuit section 41 within the telephone housing 40.

The magnetic card reader mechanism section 10 and the magnetic card reader control circuit section 20, which are connected as an integral structure in this way, are integrally attached and detached within the cashless public telephone housing 40 as shown in FIG. Guide plates 43 and 44 for guiding and fixing the outer frame plates 13 and 14 are protruded from the lower surface of the upper plate 42 of the casing 40, and the circuit boards 21 and 44 are protruded from the upper surface of the bottom plate 45 of the casing 40.
Guide plates 46 and 47 for guiding and fixing the guide plates 43, 44, 45, 4 are provided in a protruding manner, and are pushed into the housing 40 and fixed by screws or other appropriate means.
It can be fixed at 6. In addition, in FIG. 3, 48 is a front door.

In this invention, the magnetic card reader control circuit board is connected and fixed as an integral structure to both sides of the magnetic card reader mechanism section, which has a magnetic card insertion slot at the top and a magnetic card return slot at the bottom, and is integrated into the housing. Since it is made removable, it is extremely easy to install or replace the inside of the casing, and maintenance, inspection, and repair work is also facilitated. Furthermore, since it is an integral structure, mounting space can be saved, and since connections can be made using connectors inside the casing, wiring inside the casing is also simplified.
